The upper stopper portion 51 includes a head 52 which is larger than the passing groove 43 of the panel 41, and a projection 53 protruding from the head 52 and inserted into the passing groove 43 of the panel 41. Preferably, an outer diameter of the projection 53 is smaller than or approximately equal to an inner diameter of the passing groove 43. Meanwhile, a hooking groove 54 is formed on an outer surface of the projection 53. The hooking groove 54 is recessed on the outer surface of an end of the projection 53. The hooking groove 54 will be further described in the following description of the lower stopper portion 55.

The lower stopper portion 55 is coupled with the upper stopper portion 51 across the panel 41. The lower stopper portion 55 is formed with a projection accommodating part 56 to accommodate the projection 53 of the upper stopper portion 51. An inner surface of the projection accommodating part 56 is formed with a hooking protrusion 57 engagable within the hooking groove 53 of the upper stopper portion 51. Accordingly, when the projection 53 of the upper stopper portion 51 is accommodated in the projection accommodating part 56 of the lower stopper 55, the hooking protrusion 57 of the projection accommodating part 56 is hooked to the hooking groove 54 of the projection 53, thereby preventing the upper stopper portion 51 and the lower stopper portion 55 from separating from each other. Here, the hooking protrusion 57 and the hooking groove 54 are preferably disposed under the panel 41. Further, the upper stopper portion 51 and the lower stopper portion 55 may be made of an elastic material, so as to be coupled resiliently.

In the embodiment, the hooking groove 54 is provided in the upper stopper portion 51 and the hooking protrusion 57 is provided in the lower stopper portion 55, but the position of the hooking groove 54 and the hooking protrusion 57 are not limited thereto. Alternatively, the hooking protrusion 57 may be provided in the upper stopper portion 51 and the hooking groove portion 54 may be provided in the lower stopper portion 55.

Thus, the position of the upper stopper portion 51 and the lower stopper portion 55 may be exchanged with respect to the panel 41.

In the refrigerator according to the embodiment of the present invention, the shelf unit 40 further includes a decoration unit 60 provided along at least one edge of the panel 41. The decoration unit 60 may preferably be made of metal. For example, the decoration unit 60 may be provided along a front edge of the panel 41 and may be made of stainless steel. The decoration unit 60 is coupled to the panel 41 while accommodating a front region of the panel 41. Thus, the decoration unit 60 gives a beautiful and high-grade image to the shelf unit 40. Further, the decoration unit 60 may be detachable from the panel 41.

In the embodiment as shown in FIG. 2, the stopper 50 includes the upper stopper portion 51 and the lower stopper portion 55, which are fitted to each other, but the position of the upper stopper portion 51 and the lower stopper portion 55 are not limited thereto. Alternatively, the upper stopper portion 51 and the lower stopper portion 55 may be formed as a single body and may be detachably coupled to the panel 41. Further, the upper stopper portion 51 and the lower stopper portion 55 may have a screw-coupling structure.

According to the embodiment of the present invention as shown in FIG. 2, the shelf unit 40 further includes a breakaway-prevention guide 73 provided in the panel 41 preventing the shelf unit 40 from breaking away in a direction transverse to the lengthwise direction of the shelf supporter 30. In addition, a rear frame 70 is provided in the back of the panel 41. The rear frame 70 may be formed by, for example, injection molding and may be provided with the breakaway-prevention guide 73.

The rear frame 70 is placed in the back of the panel 41. The back of the rear frame 70 is shaped corresponding to the shape of a duct 13, shown in FIG. 1, through which cool air is supplied to the storage compartment 10. Here, the rear frame 70 can be made of plastic, for example, for easier processing.

The breakaway-prevention guide 73 guides the shelf unit 40 to slide and couple with the shelf supporter 30. Further, the breakaway-prevention guide 73 prevents the shelf unit 40 from breaking away from the shelf supporter 30 in the state that the shelf unit 40 is coupled to the shelf supporter 30. The breakaway-prevention guide 73 protrudes from a bottom of the rear frame 70 and is bent toward the inner wall 11 of the storage compartment 10. The breakaway-prevention guide 73 is shaped to surround the shelf supporter 30. The breakaway-prevention guide 73 may be provided at opposite end parts or one end part of the rear frame 70. A predetermined gap is provided between the breakaway-prevention guide 73 and the shelf supporter 30 so that the shelf unit 40 can be tilted to the shelf supporter 30 when the shelf unit 40 is coupled to the shelf supporter 30. Accordingly, the shelf unit 40 can be readily coupled to the shelf supporter 30.

Below, operations of the refrigerator according to the embodiment of the present invention will be described with respect to FIGS. 3 through 4C.

First, the projection 53 of the upper stopper portion 51 is inserted in the passing groove 43 of the panel 41. Then, the projection accommodating part 56 of the lower stopper portion 55 is fitted to the projection 53 of the upper stopper portion 51. When the projection 53 is fitted to the projection accommodating part 56, the hooking protrusion 57 and the hooking groove 54 are hooked to each other. Here, the upper stopper portion 51 and the lower stopper portion 55 may be made of elastic materials, so that the coupling of the hooking protrusion 57 and the hooking groove 54 are elastically maintained as being hooked. Accordingly, the panel 41 and the stopper 50 form the shelf unit 40.

Then, the shelf unit 40 slides and couples with the shelf supporter 30. At this time, the front of the shelf unit 40 is lifted up and the breakaway-prevention guide 73 is coupled to the shelf supporter 30. The shelf unit 40 is then pressed in an insertion direction, so that the shelf unit 40 is tilted to the shelf supporter 30 at a predetermined angle and guided to slide on the shelf supporter 30 by the breakaway-prevention guide 73. When the shelf unit 40 is completely inserted, the shelf unit 40 is seated on the shelf supporter 30, thereby placing the stopper 50 in the depressed groove 33. Thus, the stopper 50 is accommodated in the depressed groove 33 of the shelf supporter 30, thereby limiting movement of the shelf unit 40 in the lengthwise direction of the shelf supporter 30. Further, the breakaway-prevention guide 73 prevents the shelf unit 40 from moving in a direction transverse to the lengthwise direction of the shelf supporter 30.

As described above, the panel 41 may be made of a transparent material, and the stopper 50 includes the upper stopper portion 51 and the lower stopper portion 55 which are coupled to the passing groove 43 of the panel 41, thereby providing the shelf unit 40 with a beautiful and high grade image.

Further, the panel 41 and the stopper 50 are detachable to each other, so that the panel 41 may be replaced only when the panel 41 is damaged and the stopper 50 may be replaced only when the stopper 50 is damaged. Accordingly, the modularity is enhanced in preparation for future damage of the shelf unit 40.

Also, the decoration unit 60 is provided in the front edge of the panel 41, thereby providing a beautiful and high grade image.

Accordingly, the embodiment of the present invention provides a refrigerator of which a shelf unit has an enhanced outer appearance with various designs, thereby improving aesthetic quality.

Further, the present invention provides a refrigerator improved in modularity.
